OS NGD data has been categorised to make it easier for you to discover the data you need:
Themes: The data is structured into nine themes of related items.
Collections: Each theme is made up of one or more collections, which in turn have feature types.
Feature types: Feature types are the most granular level, with objects (features) grouped by geometry or classification.
Content in this section is ordered by themes, collections and feature types, mirroring the OS NGD data structure itself. This level of categorisation should make it easier and quicker for you to discover the data you need.
For example, if you are interested in water or river data, then you should select 'OS NGD Water' from the card below or the left-hand-side navigation menu, then drill down through the collections to the water feature type(s) that interest you.
